Erin the Robot Grrl shows an interesting application of the NFC shield.
Looking at one of my first robots, BubbleBoy, I borrowed the hula hoop idea from it… so why not also borrow the hat idea? Sweet! We could have NFC hats with RoboBrrd, where it does different things for the different hats! More super powers, new behaviours! Woot!
BubbleBoy robot and its lovely hats.
